- Аннотация: MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB 221226A ( Fermi GBM team, GCN 33104) errorbox 6665 sec after notice time and 6700 sec after trigger time at 2022-12-26 18:36:07 UT, with upper limit up to 18.0 mag. Observations started at twilight. The observations began at zenith distance = 76 deg. The sun altitude is -9.8 deg. The galactic latitude b = -8 deg., longitude l = 166 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2187618 We obtain a following upper limits.
